Hello Towertalk.

I'm planning on roof mounting a 5BTV vertical in the next week.
I'll be mounting it on an Radio Shack 3 ft. tripod and plan on 4 radials per band.
The manual tells me that I should use 2 feed line chokes, one at the antenna and one at the radio. I'm planning on using a pair of Radio Works T-4 1:1 current "line isolators" instead of the chokes.

One section of the manual has me a little confused though. The instructions say to RF isolate the antenna from the mounting mast if the mast is an appreciable fraction of a 1/4 wavelength in frequency. The tripod and mast will be 5ft tall. I've also noticed that there is no ground connection on this antenna. Is this correct?

This setup will be a temporary lash up to get me through the winter when I hope to be able to get a new tower and beam installed at the new QTH. If the vertical works well it will become my backup on the higher bands.

Thanks for the input.
